i'm a little confused...

Hi friends.!
1-i have a little question about front side bus based intel cpu
FSB : 800 mhz, that means that as i learned in one clock cycle cpu of type intel do 4 instruction so the real clock is that 200mhz,and 800 mhz is somthing like pumping.
does that correct... ??!

2-otherwise, i found in my motherboard's manual that:
front side bus : 1333/1066/800 mhz
does it mean that i can up from 800 to 1333 ?, if it does ......why (is it for overclocking ?).

Yes, they use this because it's hard to send a higher-clocked signal and keep it clean. So they send a slower reference signal, and multiply it by 4x for transmitting data.

This means the fastest clock they have to transmit is 333.3 MHz, but they can transmit data at 333.3 * 4 = 1333 MHz!

This method is still used in more modern Intel processors, it's just called the Base Clock.

Yes, it's to support faster processors sold by Intel. The early Core 2 Duo processor supported 1066 MHz FSB, and the later ones supported 1333 FSB.

Here is a 1066 model:

Intel® Core™2 Duo Processor E7500 (3M Cache, 2.93 GHz, 1066 MHz FSB) Specifications

Here is a 1333 model:

Intel® Core™2 Duo Processor E8400 (6M Cache, 3.00 GHz, 1333 MHz FSB) Specifications

And yes, you can use these faster FSB modes to overclock your 800 MHZ FSB processor!

But you'll have to tell us what motherboard you have before we can see if you can overclock or not.

Might be a little limited due to G41 chipset, but according to this it's supported by their overclock utility:



The download link on the page is dead, but I'm sure you can find it yourself if you do a bit of searching. Fox One Utility shouldn't be too hard to find.
